dc.description.abstractA dinâmica do estado adulto de Autographa gamma (L.) e Trichoplusia orichalcea (Fabricius) (Lepidoptera, Noctuidae) foi estudada entre Julho de 1988 e Dezembro de 1989, através de armadilhas luminosas do tipo pensilvânia instaladas em três localidades da ilha de São Miguel (Ribeira Grande, Arribanas e Lagoa do Congro). Para as três localidades, foram evidenciadas flutuações de densidade consideráveis. A. gamma foi observada continuamente nas três localidades, enquanto T. orichalcea foi capturada durante todo o ano na Ribeira Grande, em Fevereiro e entre Setembro e Novembro na Lagoa do Congro e entre Setembro e Dezembro nas Arribanas. Para as duas espécies, ambos os sexos foram capturados simultaneamente. O sex-ratio foi favorável às fêmeas, exceptuando para a localidade das Arribanas, onde os machos de T. orichalcea foram mais frequentes do que as fêmeas.por
dc.description.abstractABSTRACT: The adult dynamics of Autographa gamma (L.) and Trichoplusia orichalcea (Fabricius) (Lepidoptera, Noctuidae) were studied between July of 1988 and December of 1989, at Ribeira Grande, Arribanas and Lagoa do Congro on the island of São Miguel, using Pennsylvania backlight traps. Despite evidence for considerable density fluctuations, A. gamma was continuously present at the three locations. In contrast T. orichalcea was only captured the whole year at Ribeira Grande, during February and from September to November at Lagoa do Congro, and from September to December at Arribanas. For any given species both sexes were captured simultaneously. In T. orichalcea males were more frequent than females only at Arribanas while at the other localities females of this species and of A. gamma were more abundant.en
